Hi,
I am still working on the design of the basic hand controller, so I don't have an immediate timeframe. I am hoping to have them ready around the same time as the next AstroEQ batch (end of May). While a simple design is possible, part of what is holding me up is finding a suitable and simple way to assemble hand controllers into a suitable enclosure. I have found one enclosure which will hopefully work very nicely but they have been on back order for the last month but have finally shipped today. Until I have those to verify all of the dimensions I am holding off ordering the boards.
In the mean time I am in the process of finalising the V8.0 firmware release at which time I will release schematics for a push button hand controller so you will be able to make your own. I am planning a release just after Easter (I have a few days off over Easter so I have time to finish stuff off).
Kind Regards,
Tom.
